Potential biodegradation of polycyclic aromatic hydrocarbons (PAHs) and petroleum hydrocarbons by indigenous fungi recovered from crude oil-contaminated soil in Iran

mycolabadmin

Scientists isolated fungi from oil-contaminated soil in Iran to find species that can break down petroleum pollutants. Two fungi species, Alternaria tenuissima and Epicoccum nigrum, showed exceptional ability to degrade harmful oil compounds called PAHs. When applied to contaminated soil in the laboratory, these fungi successfully eliminated over 70% of the long-chain hydrocarbons. This research offers a natural and cost-effective way to clean up oil-spilled soil without using harsh chemicals.

Revitalization of the Endophytic Fungus Acremonium sp. MEP2000 and Its Impact on the Growth and Accumulation of Bioactive Compounds in Inonotus obliquus

mycolabadmin

Researchers successfully revived a beneficial fungus called Acremonium sp. MEP2000 that had lost its effectiveness through repeated cultivation by adding birch bark powder and medicinal mushroom powder to its growth medium. When used to treat the medicinal fungus Inonotus obliquus (chaga), this revitalized fungal culture dramatically improved the growth and production of healthy bioactive compounds like polysaccharides and triterpenoids. This breakthrough offers a practical solution for large-scale production of medicinal fungi with enhanced therapeutic potential for treating cancer, diabetes, and inflammatory conditions.

Novel method for rapid monitoring of OPFRs by LLE and GC–MS as a tool for assessing biodegradation: validation and applicability

mycolabadmin

This study developed a new analytical method to detect and measure organophosphate flame retardants (OPFRs) in water samples. Researchers tested whether certain fungi, particularly white-rot fungi like Ganoderma lucidum and Trametes versicolor, could break down these toxic chemicals that are difficult to remove by conventional water treatment. The results show these fungi can effectively degrade some OPFRs, offering a promising biological treatment option for contaminated wastewater.

Statistical optimization of crude oil bioremediation using Streptomyces aurantiogriseus isolated from Egypt’s Western Desert

mycolabadmin

Researchers from Egypt isolated a special type of bacteria called Streptomyces aurantiogriseus that can break down crude oil and remove it from contaminated soil. Using scientific optimization techniques, they found the best conditions for this bacteria to work most effectively, achieving 92% oil removal in soil experiments. This eco-friendly approach offers a sustainable solution to clean up oil-polluted environments without harmful chemicals.

Chemical profile and bioactivity of essential oils from five Turkish thyme species against white mold fungal disease agent Sclerotinia sclerotiorum

mycolabadmin

Researchers tested essential oils from five different thyme species grown in Turkey against a common plant fungus that causes white mold disease. They found that oils rich in carvacrol, particularly from Thymbra spicata and Satureja cilicica, were very effective at stopping fungal growth. These natural oils could be used as environmentally friendly alternatives to chemical pesticides in farming.

Characterization of the changes of aroma profiles in large-leaf yellow tea during processing using GC–MS and electronic nose analysis

mycolabadmin

This study examined how large-leaf yellow tea develops its distinctive fried rice-like aroma during processing. Researchers identified 178 different volatile compounds throughout eight processing stages using advanced analytical techniques. The full fire roasting step was found to be most important for creating the final roasted and nutty flavors, generating 30 new nitrogen-containing compounds. An electronic nose device successfully tracked these aroma changes in real-time, suggesting it could be used for quality control in tea production.

Honeybee associated Aspergillus niger AW17 as a source of selective anticancer compounds with cytotoxicity evaluation in human cancer cell lines

mycolabadmin

Scientists discovered that a fungus found in honeybees can produce compounds that effectively kill cancer cells while leaving healthy cells largely unharmed. The fungus (Aspergillus niger AW17) contains unique bioactive compounds including high levels of oleic acid and a rare compound called pachymic acid. When tested against four types of human cancer cells, the fungal extract was particularly effective against liver and colorectal cancer. This finding suggests that exploring specialized environments like beehives could lead to new cancer treatments with fewer side effects.

Chilean Aloysia Essential Oils: A Medicinal Plant Resource for Postharvest Disease Control

mycolabadmin

Researchers tested essential oils from two Chilean herbs, Aloysia citriodora and Aloysia polystachya, against fungi that cause fruit rot after harvest. They found that oil from Aloysia citriodora, especially a compound called farnesol, effectively killed the disease-causing fungi in laboratory tests. These natural oils could replace synthetic fungicides that are becoming less effective and harmful to the environment, offering farmers a safer way to protect their fruit during storage and transport.

Fermentation Characteristics, Antinutritional Factor Level and Flavor Compounds of Soybean Whey Yogurt

mycolabadmin

Researchers developed a method to turn soybean whey (a waste product from tofu and soybean protein production) into delicious plant-based yogurt. By removing salt through electrodialysis and concentrating the whey, then fermenting it with yogurt bacteria, they eliminated the unpleasant beany flavors and harmful compounds that make raw soybean products unappetizing. The resulting yogurt has a creamy texture, pleasant flavor, and better nutrition compared to untreated soybean whey, offering an environmentally friendly way to use agricultural byproducts.

Do farnesol and tyrosol production in Candidozyma auris biofilms reflect virulence potential?

mycolabadmin

Researchers discovered that a dangerous fungus called Candidozyma auris produces signaling molecules called farnesol and tyrosol in biofilms. These molecules appear to be linked to how dangerous the fungus is—strains that produce more of these molecules were more virulent in infection studies. Understanding these signaling molecules could help develop new strategies to fight this drug-resistant pathogen.
